Purpose : The purpose of this study was to evaluate influence of therapeutic exercise on functional leg length inequality(LLI). Methods : The subjects were consisted of thirty patients who had Leg length inequality(LLI) of more than 10mm(l6 females. 14 males) from 20 to 35 years of age(mean aged 24.23). All subjects randomly assigned to contract-relax exercise of proprioceptive neuromuscular facilitation(PNF) group(n=15), control group(n=15). Contract-relax exercise group received contract-relax exercise about 10 minutes with therapeutic massage about 15 minutes for 3 times per week during 4 weeks period. Control group not received intervention during 4 weeks period. The tape measure method(TMM) was used to measure functional Leg length inequality. Biodex System 3 Pro was used to measure strength of Knee extension & flexion. All measurements of each subjects were measured at pre-test, 2weeks post-test and 4weeks post-test. Results : 1. The LLI of contract-relax exercise group was significantly reduced according to within treatment period(p<.05), most significantly reduced between pre-test and post-test(p<.05). Contract-relax exercise group significantly more reduced than control group(p<.05). 2. The knee extension strength of contract-relax exercise group was significantly increased according to within treatment period(p<.05), most significantly increased between pre-test and post-test(p<.05). Contract-relax exercise group significantly more increased than control group(p<.05). 3. The knee flexion strength of contract-relax exercise group was significantly increased according to within treatment period(p<.05), most significantly increased between pre-test and post-test(p<.05). Contract-relax exercise group significantly more increased than control group(p<.05). Conclusion : Contract-relax exercise applied with therapeutic massage can reduce LLI and increased lower extremity muscle strength.

Purpose: This study was conducted to examine the effect of education on infection control for multidrug resistant organism (MDRO). Methods: One group pre-post time series design was used. Infection control education for MDRO infection was provided to nurses working in the Neonatal Intensive Care Unit (NICU). Knowledge and recognition were evaluated before and after education. Hand hygiene compliance, MDRO isolation rate and central line-associated bloodstream infection (CLABSI) rate were used as outcome variables. Data from 45 nurses was used for analysis. Results: General knowledge about MDRO increased (p=.011). Responses to questions about image of MDRO and MDRO management tended to change in a positive direction (p=.046). Hand hygiene compliance was 100% at pre-test, 79.5% during education period and 98.4% at post-education period. MDRO isolation rate was 6.83 per 1,000 patient days at pre-test, 10.24 during education period and 6.68 at post-education period. CLABSI rate was 3.76 per 1,000 central line days at pre-test, 6.84 during education period and 4.71 at post-education period. Conclusion: Findings indicate that the education program is effective in improving knowledge about MDRO in NICU nurses. However, more reliable indicators should be used to determine long-term effects.

본 연구는 반성방법의 차이에 따른 예비 지리교사의 수업전문지식 변화를 파악하는 데 목적을 두고 있다. 연구 목적을 달성하기 위해 l차 모의수업 결과를 토대로 통일한 수준에 있는 데 명의 예비교사들을 선정한 후, 각각 상이한 반성을 거쳐 2차 모의수업을 실시하도록 하였다. 이 때 각각의 수업에 대한 동료평가를 실시함으로써 예비교사들의 수업전문지식 구비정도를 파악했고, 1차 및 2차 수업 간의 점수를 비교함으로써 반성방법의 차이에 따른 수업전문지식의 변화 양상을 파악했다. 연구 결과는 다음과 같다. 먼저, 1차와 2차 모의수업을 비교해본 결과 모든 예비교사의 평균점수가 상승했지만, 반성하지 않거나 자기반성을 행한 예비교사에 비해 전문가와의 협력적 반성을 행한 예비교사의 점수가 큰 폭으로 향상되었다. 다음으로 자기반성을 통해 반성적 성찰지를 작성한 예비교사의 경우 반성적 사고는 가능했지만 반성적 실천으로 이어지는 데에는 한계가 나타났다. 마지막으로 통계적으로 유의미한내용지식의 향상은 전문가와의 협력적 반성을 행한 예비교사에게만 나타났다. 특히 영역과 학습자에 대한 이해 영역에서 유의미한 통계 값이 나타났다. 이를 통해 내용이나 상황영역 부문은 예비교사 스스로의 자기반성 및 반복적 수업 실연을 통해서도 향상될 수 있지만, 영역과 학습자에 대한 이해 영역은 조력자의 도움이 필요하다는 사실을 도출할 수 있었다.

The determination for bearing capacity of precast nodular piles is conventionally time-consuming and high-cost by using numerous experiments and empirical methods. This study proposes an intelligent method to evaluate the bearing capacity and shaft resistance of the nodular piles with high efficiency based on long short-term memory (LSTM) approach. A series of field tests are first designed to measure the axial force, shaft resistance and displacement of the combined nodular piles under different loadings, in comparison with the single pre-stressed high-strength concrete piles. The test results confirm that the combined nodular piles could provide larger ultimate bearing capacity (more than 100%) than the single pre-stressed high-strength concrete piles. Both the LSTM-based method and empirical methods are used to calculate the shift resistance of the combined nodular piles. The results show that the LSTM-based method has a high-precision estimation on shaft resistance, not only for the ultimate load but also for the working load.
